This was a question asked in IRC, someone wanting a way to have the parent
function
name outputted for logging purposes. Just like there is __LINE__ and __FILE__
for
access to the line number and filename, would be handy (and trivial to
implement)
if there was a __FUNCTION__ variable also for outputting the bare name of the
function. Optionally could also add a __PRETTY_FUNCTION__ too for outputting the
type signature of the function.

ie:
writeln(__FUNCTION__); // foo
writeln(__PRETTY_FUNCTION__); // int foo(string)

I have seen this enhancement request many times. Time ago I have also suggested
a reference to the function itself, to be used in self recursive functions.

Yah, we need such. To help with generic code, I'm hoping for:

function.stringof
module.stringof
class.stringof
struct.stringof
union.stringof
enum.stringof

to yield the name of the current entity.

Yea, I don't even care what the syntax for it is; it's such a frequent 
request, there should at least be some way to invoke it.

__FUNCTION__ exists in C++. I added a feature request for it a couple of months 
ago: http://d.puremagic.com/issues/show_bug.cgi?id=5140
